The Company’s non-qualified stock options, RSAs and RSUs, are equity awards with service-only conditions and are accordingly expensed on a straight-line basis over the vesting period. For equity awards with performance and market conditions, the Company uses the graded-vesting method of expense attribution. Compensation cost is recorded net of estimated forfeitures, which are adjusted as appropriate.
